Description by Sean Moses Written by the developer, not by AppBrain. Click to read.
Ever wonder how people play music with a number? 1 to A makes sense of the number system and shows you the translation for all major keys. Simply select a key and see the chord that corresponds! Don't know how to play that chord? We got you just click on the number and view the fingering!
